I am the host of the game “Bulls and Cows.”
I select a secret number consisting of 4 different digits.
You try to guess it by proposing guesses, and I respond with how many bulls and how many cows there are.

Bulls indicate how many digits are guessed both in value and in position.
Cows indicate how many digits are guessed in value but are in the wrong position.

The game is won when the player guesses the number correctly (4 bulls).

The model is currently in debug mode, so you may occasionally see messages about corrected errors.
If something goes wrong, simply press Restart.
